JAY-W. MOORE, OF GAYS MILLS, WISCONSIN, ASSIGNOR TO STOEL'I'ING BROTHERS 00., OF KIEL, WISCONSIN.

CARRIER.

To all whom it may concern:

Be it known that I, JAY 7. Moon, a citi- Zen of the United States, and resident of Gays Mills, in the county of Crawford and State of Wisconsin, have invented certain new and useful Improvements in Carriers; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its primary object to provide simple, effective and economically constructed automatic reversing mechanism for endless belt-driven carriers, to which may be attached any form of agitator, hopper or analogous device.

The invention further contemplates providing means for effecting a change of position of the carrier device incidental to change of direction of its travel, the invention being particularly applicable to a curd stirring device or shovel that is arranged to travel back and forth within a vat containing such product.

Specific objects of my device are to provide a shackle connection between the endless belt and carrier; to provide a link connection between the shackle and carrier device, whereby change of position of the same is effected incidental to the reversal of the direction of travel of said carrier, which reversal is effected as the belt turns.

l/Vith the above objects in view my invention consists in certain peculiarities of construction and combination of parts as hereinafter set forth with reference to the accompanying drawings and subsequently claimed.

In the drawings Figure 1 represents a side elevation of a carrier embodying the features of my invention, the carrier being shown connected to a curd-stirring device or shovel arranged to travel back and forth in the vat; Fig. 2, an enlarged detail elevation of the upper portion of the carrier mounted upon a track section, having parts broken away and parts in section to more clearly illustrate the invention, Fig. 3, a sectional end view of the same, the section being indicated by line 33 of Fig. 2; Fig. 1, a de- Specification of Letters Patent.

Serial No. 601,811.

tail plan section as indicated by line 14: of Fig. 3, and Fig. 5, a detail face view of the carrier shackle with its chain attaching link in section as indicated by line 55 of Fig. 3.

Referring by characters to the drawings, 1 represents an inverted U-shaped track having inturned edges that constitute track members for the support of a trolley 2, wheels 3 of which trolley are adapted to travel upon the track. Hangers 4, 4, depend from the track member for the support of arbors 5, 5*, upon which arbors are mounted sprocket-wheels 6, 6. Power is applied to the drive-sprocket 6 by a sprocket-wheel 7 that is also fast upon the arbor 5, as shown in- Fig. 1, the drive and driven sprockets 6 and 6 serving as supports for an endless link-belt 8 which is disposed under the track member and parallel therewith. v

The carrier is provided with a depending shank 9 upon the upper end of which is slidably mounted a sleeved shackle -10 having a project-ing stud 11 upon which is swiveled an eared chain link 12 that constitutes one member of the endless belt, the same being recessed for the reception of the sprocket-teeth incidental to the travel of said link about the drive and driven sprockets. As shown in Fig. 1, the shackle connection between the endless belt and carrier shank is upon the upper stretch of said chain, the same being illustrated as traveling in the direction indicated by the arrow, in which position the shackle is locked with relation to the carrier shank by a spring-controlled catch 13, the upper end of the catch being in hinge connection with the carrier while its lower end is provided with a locking nose 14 adapted to engage the upper and lower edges of the shackle sleeve whereby the same is locked when traveling uponthe upper or lower stretches of the endless belt. A tappet 15 in the form of a roller extends from the lower end of the spring-controlled catch 13, the said tappet being adapted to engage fixed cams 16, 16 which arepermanently secured to the track-member by upwardly extherefrom an ear 22 to which is pivoted one end of a link 23, the opposite end thereofbeing pivoted between ears 24; that extend from the shackle sleeve.

Referring to Fig. 2, a carrieris shown as' traveling upon the lower stretch of the belt in the direction indicated by the arrow, the sleeve being locked between the nose 14 of the catch and a shoulder 9 of the carrier shank. In this position the chain link 12, which is in swivel connection with the shackle, has just engaged a tooth of the driven sprocket 5 and incidental to its engagement, the tappet roller 15 has engaged and traveled up an inclined face of the cam 16, whereby the nose 14 of said catch is freed from its engaged position with the upper edge of the shackle sleeve. The

shackle is now free to slide upon the carrier shank and, as the chain link 12 rotates,

about the sprocket wheel, the nose of the catch travels upon the face of the shackle sleeve and is thereby held in its extended position, the sleeve in the meantime having moved upon the shank to the position indicated in Figs. 3 and 1, whereby the shackle is shifted from the upper to the lower belt stretch. The direction of travel of the carrier, owing to the crank movement imparted by the sprocket-wheel to the shackle, is.

thus reversed and said carrier now starts upon its return movement. Incidental to the shift of the shackle from the lower to the upper belt stretch, the link connection 23 between said shackle and agitating device causes the same to reverse its inclination to theposition shown in full lines Fig. 1. The tappet roller travels back over the cam and down the incline to the position as indicated at A, Fig. 4;, and the nose portion thereof is thereby forced by spring pressure under the lower edge of the shackle sleeve as indicated in dotted lines, Fig. 3. The shackle sleeve being new locked in its upper position, will relieve the driving belt of all strain and at the same time securely lock the curd agitator at the proper angle to plow through the curd contained in the trough whereby the same is split into shreds as it passes between the grid bars. When the carrier reaches the belt turn at the driving end of the track, the tappet will engage cam 16 whereby the shackle is unlocked from the carrier shank and the reverse move ment is repeated, causing the curd-agitator to assume the position as indicated by dotted lines in Fig. 1.

From the foregoing description it will be seen that the carrier is moved back and forth due to its belt connection and that a shift of position of the agitator or other device is obtained simultaneous with the shift of direction of travel of said carrier, and, while I have shown and described the carrier asbeing provided with a curd agitator it is apparent that any form of hopper s iral or analogous device may be suspended rom said carrier and the link 23 connected thereto is operated to change the position or effect some mechanical movement incidental to the reverse of travel. Y

The combined carrier and agitator mechanism herein disclosed has been made the subject of a separate application filed by me June 29, 1911, Serial No. 636,119.

I claim:

3. In a track-supported carrier having an endless belt-drive, a shackle connecting the belt and carrier, means for locking the shackle to the carrier, and fixed releasing means, for the shackle lock disposed adjacent to the belt turns.

4. In a track-supported carrier having an endless chain-belt, and a drive and driven sprocket-wheelfor the belt; a reverse mechanism for the carrier comprising a shackle in connection with the carrier and in swivel connection with one of the chain links.

5. A carrier comprising a track, a trolley having a depending shank mountedthereon, an endless belt disposed parallel with the track, a shackle carried by the belt in sliding engagement with the shank, a locking spring for the shackle, a tappet extending therefrom, and fixed cams disposed at the opposite belt-turns for engagement with the spring tappet.
